Re: [Boost-users] [Serialization]: SIGSEGV on Mingw32, during global static data initialization (runs ok on Linux)

Just out of curiosity? are you doing multi-threading?

  Hi,

  I've been using boost Serialization library (release v1_33_1) on Linux without problems, with g++ compiler of both v3.3.6 & v4.1.1.  My program serialzes boost::shared_ptr of polymorphic types, and BOOST_CLASS_EXPORT() and BOOST_SERIALIZATION_SHARED_PTR() are used.   

  However, when the same program is ported & run on mingw32 (w/ g++ v3.4.5 on WinXP), it generates SIGSEGV before my main() is called.  and here's the stack trace:

  Program received signal SIGSEGV, Segmentation fault.
  0x6e3759a3 in boost::archive::detail::basic_serializer::basic_serializer (
      this=0x4, eti=@0x813484)
      at /opt/boost/boost_1_33_1/boost/archive/detail/basic_serializer.hpp:37
  37          {}
  (gdb) bt

  #5  0x00404568 in main (argc=1, argv=0x3d45f8) at ../../src/HmcMain.cpp:231
  (gdb)

  I cannot connect the logic between stack frame #3 and #2; it seems trying to instantiate some global static data when SIGSEGV happens.  Is there some dependency on order of global static data initialization  to be satisfied for using BOOST_CLASS_EXPORT/BOOST_SERIALIZATION_SHARED_PTR? HmcBase is the base class for my polymorphic types, and all my code are statically linked, while "boost_serialization-mgw-d-1_33_1.dll" is used here.    I saw some discussion in this mailing list on "Serializing classes defined in DLLs" a year ago, but don't know what's the current status on it and whether this case is related to it. 

  Thanks for any hit,

  --- Jeffrey
